Norröra is often called Saltkråkan after the filming of Astrid Lindgren's "Vi på Saltkråkan" (We on Seacrow Island). The name Norröra comes from the word "ör" meaning gravel and sand, which is exactly what there is plenty of on the ground of this island. This has made it possible to cultivate the land, and there has been farming here since the1500s. Otherwise, hunting and fishing were the main food sources, as they have been for most of the other islands in the archipelago. Today, there are no year-round residents on the island. Old buildings are used as cottages. Guided tours are available for those who want to experience more of the island and life on "Saltkråkan."
